Application December 17, 1951, Serial No. 262,013 4 Claims. c1. z-ssThis invention relates to garments of deposited latex which arefashioned to be buttoned on when in use so that they can be put on andtaken off the wearer with greater facility than similar latex garmentswhich have to be stretched in the process of getting them on or off thewearer.

Garments of deposited latex are usually thin and can be stretched butlack the mechanical strength of such materials as woven fabrics.Difliculties have therefore been experienced in attempts to providegarments of this kind with fastening elements such as buttons or thelike, owing to the tendency on the part of such fastening elements totear the material or to work loose when stress is applied thereto.According to the present invention, buttons are mounted on the garmentsin such a way that they do not come loose, nor are they so apt to tearthe fabric. While the invention may be used in various kinds ofgarments, its use in connection with baby pants and womens girdles ishereinafter described and is illustrated on the drawings, of which-Figure 1 is a front view of baby pants opened out;

A button such as is used in the garments illustrated in the drawing isshown in Figure 8 and consists of an oval piece 30 of stiff sheetmaterial such as metal or a synthetic resin. Two parallel slits 32 and34 are cut in the oval piece 30 and the strip 36 of the material betweenthe slits is sprung out of the plane of the rest of the buttonsufficiently to admit the end portion of a strap 40 which is of softrubber such as deposited latex and is highly stretchable or extensible.The strip 36 is then pressed back to the plane of the rest of thebutton, thus pinching the strap 40 in two places where it passes throughthe slits. Since the material of the strap is highly extensible, itfollows that the strap becomes thinner when subjected to longitudinalstresses and elongated, so that it is apt to pull out of the slits. Toprevent this, I insert a stop member such as a strand 42 shown in Figure6 or a strip 44 as shown in Figure 7. These stop elements extendtransversely with respect to the strap and are embedded in the materialthereof, being preferably located near the free end of the strap, thatis, between the extremity of the strap and the nearest slit of thebutton. This strand 42 or strip 44 is preferably of a material whichdiffers from the material of the strap itself. For example, it may be ofrubber which is somewhat stiffer than the soft rubber of the strap, orit may be a strand of textile fibres, or a wire of metal, plastic orothermaterial. The strand 42 or the strip 44- prevents the end portionof the strap from pulling back through the slits 32 and 34 when tensionis applied to the strap. The strand or strip may be incorporated in thestrap in the manner hereinafter described. it

The button is used to secure together portions of a garment by beingthrust through a suitable button-hole which may be in the form of a slit46 in the garment. In order to reinforce the slit 46 an oval patch 48(Figure 11) may be applied to or embedded in the material of thegarment. For example, Figures 1, 3 and 4 illustrate baby pants which maybe formed by dipping a suitable form 49 into a pool of prepared latexand allowing the deposited film of latex to dry on the form. The dippingand drying steps are repeated until a sufficient thickness of latex hasbeen deposited. The latex may be a prepared latex mixture ready to bevulcanized When coagulated or may be pre-vulcanized so that when itdries it becomes a vulcanized film. The baby pants shown in Figures 1, 3and 4 consist of a sheet or film of deposited latex or the likeconsisting of two relatively wide portions 5% and 52 connected by anarrower neck 54. In the form of baby pants illustrated in Figure 1 theportion 56 has inturned side margins 56. These are formed by depositinga latex film on both faces of the form which is approximately the samecontour as that of the opened out baby pants shown in Figure 1. The filmon the front face of the form is cut away to leave the garment shown,the upper portion of this garment being cut to form a series of straps60 to the ends of which are secured buttons 30 in the manner described.In the lower portion 52 button-holes 46 are provided so that when thelower portion is brought up to overlie the upper portion, the pants maybe buttoned up as illustrated in Figure 3 leaving the apertures 62 forthe legs of the infant.

The reinforcing patches 48 may be incorporated in a garment by beingapplied to the film on the form resulting from an initial dip. Thepatches are applied at the proper places and readily adhere to thesticky film. Subsequent dipping serves to cover the patches and to embedthem in the material of the garment as indicated in Figure 9. Ifdesired, each patch may be reinforced by a loop 64 of wire, thread, orother suitable material embedded therein. As illustrated in Figure 11,the patch is made with a thin central portion where the slit is to bemade. This thin central portion is surrounded by a rounded ridge 66which tapers outwardly in thickness to a thin edge 68, so that when thepatch is embedded in a garment, the surface contour of the garment aboutthe patch is smooth.

When the buttons are pushed through the button-holes 46, they lie fiatagainst the surface of the garment in the vicinity of the button-hole.The buttons may be inserted from the inner to the outer surface of thefront flap 52 as illustrated in Figures 3 and 4 or, if preferred, may beinserted from the outside in so as to be held between the inner surfaceof the flap 52 and the body of the infant.

In order to incorporate stop elements 42 in the straps 40, a strand 70is mounted on the form 49 before the dipping begins. Portions of thestrand are held away from the surface of the form by spacing elements 72on the face of the form so that when the form is dipped, the latex willsurround and embed such portions of the thread. To hold the threadfirmly against the spacers 72 the thread is caught under fingers 74which overhang depressions 76 in the face of the form. Recesses andspacers may be arranged on the form in the manner shown in Figure 12.The form is then dipped as often as desired to accumulate a film ofsuitable thickness thereon. After the film has been dried, vulcanizedand stripped from the form it is then cut along the broken lines 84shown in Figure 12. This cuts away portions of the strand 70, theremaining portions being embedded in the straps which are formed by thecut 84.

A slightly different form of baby pants is shown in Figure 16. The blankfrom which these baby pants are made, the upper portion of which isshown in Figure 15, is in a single plane and can be cut from sheetstock. If preferred, a form can be dipped and two blanks can be made onone form, the front and rear portions of the film deposited on the facesof the form being simultaneously trimmed along the margins to form thestraps 40 shown in Figure 15. A portion of a suitable form 78 isillustrated in Figures 17 and 18, the strand being applied to both facesof the form. In this case spacing blocks 72 are attached to both thefront and rear faces of the form and holes 86 extend through the formitself to receive the strand 70. The strand is threaded through theholes as indicated in Figure 18 so that stretches of the strand aresupported in taut condition between successive spacers 72. When thedipping has been completed, the strands are cut at the holes 86, thefilm is stripped from the form and laid fiat, and the front and rearportions are simultaneously cut by a suitable die to form a shape theupper portion 88 of which is illustrated in Figure 15, the lower portion90 being shown in Figure 16, provided with button-holes 46.

The invention may be employed in other kinds of garments such as thegirdle 92 illustrated in Figure 19. Girdles of deposited latex haveheretofore been made in a tubular shape of varying circumference to bestretched when put on the wearer and when taken off. It is sometimesdifficult to put on a girdle by that method which involves considerablerisk of tearing the material and ruining the girdle. Hence, according tothe invention, I supply a split girdle having margins to be buttonedtogether after the girdle has been applied to the body of the wearer.The girdle is preferably formed by dipping a suitable form in a pool oflatex in the customary manner. The deposited film is thereafter trimmedand is slit from top to bottom, button-holes 46 being formed at one sideof the slit and straps 40 being formed to project from the other side ofthe slit. Buttons 30 are then mounted on such straps. Button-holes 94may also be provided along the lower margin of the girdle for thesupport of garters (not shown) and a crotch piece 96 (Figure 27). Asshown, each end of the crotch piece is trimmed to form three shortstraps 40 with a stop element 42 in each strap, and a button 30 issecured on the end portion of each strap, one such button being shown inFigure 27. Figure 21 shows a girdle as it comes from the form after theslit has been cut and one margin has been cut to form the projectingstraps for the buttons. Since it is desirable that the margin having thebutton-holes overlie the buttons when the garment is laid flat on asupporting surface, one or both side margins of the form itself arecurved out of the plane of the form so as to provide extra width to thefront portion of a deposited latex girdle as compared with the rearportion thereof. Figure 28 shows in horizontal section a form 98, theside margins 100 of which are curved out of the plane of the form sothat the horizontal dimension of the front portion of the film depositedon the form is considerably greater than the corresponding horizontaldimension of the rear portion of the film. Thus when the film isstripped from the form and laid flat on the supporting surface therewill be extra width in the front portion which can be used to permit themargin with the button-holes to overlap the end portions of the straps40 which carry the buttons when the garment is lying flat.

Figure 22 shows in section the shape the film has when it is on a formhaving one side margin curved out of the plane of the form. Since formsfor this kind of garment are customarily metal slabs about one-half inchthick, the curvature of the film at the edges of the form is relativelysharp, as indicated at 101 in Figure 22. The curvature of the film whereit followed the curved marginal portion of the form, as at 102, is moregradual so that when the garment is laid on a fiat surface, thecurvature 102 is not sufficient to make it hump up, but it takes a shapesomewhat as shown in Figure 20, although actually most of the upperlayer would then rest on the lower layer.

Figure 23 illustrates a girdle 103 which is partially slit, that is, theslit extends down from the upper portion part way toward the wider lowerportion. The margin at one side of the slit is provided with suitablebutton-holes to cooperate with buttons 30 mounted on straps 40 formed bycutting away portions of the margin on the other side of the slit. Sinceit is desirable that the finished garment lie fiat when the button-holesare registering with the buttons, extra width is provided for the frontportion of the garment by curving the upper portion 104 of one of theside margins of the form 106 out of the plane of the form as indicatedin Figure 25. This results in a girdle blank shaped as shown in Figures24 and 26, Figure 24 showing the blank after the slit has been cut andone margin has been trimmed away to form button straps. When therearwardly curved portion 108 of the blank has been straightened as whenthe blank is laid on a horizontal supporting surface, the margins of theslit having button-holes will then overlie the buttons due to the extrawidth provided by the curved portions.
